The invention relates to a bottom shaft driven turnover board gate, in particular to a bottom shaft section connecting device of turnover board gate, and aims to provide a connecting device capable of ensuring synchronous double-side transmission of bottom shaft connection while eliminating the influence of bottom shaft shrinkage caused by temperature variation/stress deformation-induced linear expansion on pier-passing and water sealing. The bottom shaft section connecting device comprises an outer engagement unit arranged at each bottom shaft section connection position, a pair of transition connection sleeves and a pair of inner engagement rings connected with the transition connection sleeves, wherein a gap exists between the two inner engagement rings, the two inner engagement rings are engaged with the same one outer engagement unit, and a seal ring is arranged at the radial outer part of the inner engagement ring and between the two transition connection sleeves to stop water.
